How Government Redlining Maps Encouraged Segregation in California Cities [Interactive]

A Supreme Court decision last June made clear that housing discrimination is not just a thing of the past.

In a 5-4 decision, the High Court ruled that even unintentional housing discrimination violates the Fair Housing Act. Homeowners or renters, it stated, can file suit against government or private housing policies without having to prove that alleged discriminatory act was done intentionally.

Writing for the majority, Justice Anthony Kennedy said that although legally sanctioned racial segregation is over, “its vestiges remain today, intertwined with the country’s economic and social life.”

He did not, however, elaborate on the various federal government policies in place before the Civil Rights Movement that actually encouraged housing discrimination and segregation. It’s these policies, some historians argue, that helped determine the demographic makeup of the neighborhoods many of us live in today.

One example is the Home Owners’ Loan Corporation (HOLC). Established by Congress in 1933, the initiative was promoted by President Franklin Roosevelt to help stem the urban foreclosure crisis that had spiked during the Great Depression.

Over the next three years, the federal agency refinanced more than a million homes. It issued low-interest, long-term loans to scores of new homeowners across the nation, spurring a dramatic uptick in home-ownership over the proceeding decades.

But only for some.

To show which areas were safe investments,  HOLC gathered reams of local data to draw up “residential safety maps” of cities across the nation. Neighborhoods were classified into one of four categories based on “favorable” and “detrimental” influences. Factors included terrain and type and age of buildings,  as well as the “threat of infiltration of foreign-born, negro, or lower grade population.”

palette“A” areas, in green, were  considered “hot spots,” where good mortgage lenders … are willing to make their maximum loans.” “B” areas,  in blue, were deemed not as desirable, but “still good.” “C” areas, in yellow, were considered in decline. And finally, “D” areas, in red, were considered to be in full decline, areas lenders should steer clear of.

Not surprisingly, HOLC’s  classification method was heavily influenced by a neighborhood’s racial and economic demographics.

Private banks quickly adopted the government’s identification system, commonly denying home loans to residents in neighborhoods considered risky. The color-coding of maps became a verb: to redline a community was to mark it as undesirable and not worthy of investment.

Below are some of the original HOLC maps and re-created interactive versions, which use data collected by the University of Maryland’s T-Races project. Created in the late 1930s, they illustrate HOLC’s neighborhood classification system for mid-to-large cities in the Bay Area and elsewhere in California.

University of Richmond Historian Robert K. Nelson, who runs the  Redlining Richmond project describes the methodology:

Neighborhoods inexorably declined as housing stock decayed and housing styles went out of fashion, lowering values to the point that a “lower grade population” began “infiltrating” the neighborhood. This was bad enough when those infiltrators were working-class or foreign-born whites. Their presence compromised the neighborhood’s social homogeneity and accelerated the decline of both housing values and neighborhood desirability.

The movement of African Americans into a neighborhood was far worse according to this model, precipitating the final demise of its desirability and “residential security.” Thus while HOLC grades were assigned by weighing a variety of factors, including the age of houses and the fashionability of particular architectural styles, it is clear that race trumped all others …

Although officially prohibited by the Fair Housing Act of 1968, the  practice of neighborhood delineation based on race and class had a lasting impact, depriving certain neighborhoods of essential resources. And that many argue, helped determine the demographic and economic makeup of the neighborhoods we live in today.

More subtle forms of redlining continue however, as evidenced by recent discriminatory loan practice settlements  and issues of “retail redlining,” wherein businesses avoid setting up shop in neighborhoods deemed undesirable.

    Though I’ve known this existed for years (sociology major here!) it’s fascinating to see these maps. I currently live in an area of Oakland that was designated “C” or yellow. Before this, I rented a room in a house which was a “D” or red area. From my personal living experiences, the red area suffered more damaging consequences to this type of segregation than did the yellow area I live now.

  • Banks wanted these policies so they could make mortgages of longer than five years. From their view, zoning protects value. Other predatory financers worked inside the off limits neighborhoods. This has been researched in the Chicago area. Gerald Horne’s work should be studied to understand the creation of whiteness going back to colonial times as a foundation for American racism.

    these problems are still going on…take a look at these maps of OneWest foreclosures in Los Angeles- they’re concentrated in communities of color: https://badbankmerger.com/maps/ Also including picture of OneWest bank branches in LA- and the communities they’ve avoided.

  • FYI – the Urban Oasis Project link is now owned by someone else. All of the known HOLC maps are now available at the comprehensive project site, http://www.mappinginequality.us
